GoivrPEI KUWADA, or KoBE, JAPAN.

METAL-PLANER.

T o all whom it may concern:

Be it known that l, GOMPEI KUwADA, a subject of the Japanese Emperor, residing at Kobe, Japan, have invented certain new and useful improvements in Metal-Planers, of which the following is a specification.

My invention relates to metal-planing machines, and consists more particularly in an improved mechanisn for reversing the tool at the end of each stroke of the table, so that the tool cuts on both strokes. When desired, however, the planer may be used in the ordinary way, by disconnecting the reversing mechanism.

I am aware that it is old to provide means for so reversing the tool at each stroke, my invention consisting, as stated above, in the particular mechanism employed, which comprises positively actuated means for rotating the tool-holder through 180o at the end of each stroke, said. means being operativelyl connected to the cross-feed mechanism, so that said parts are positively correlated in their action, that is, neither can operate without the other, when it is desired to have the tool cut on both strokes. Furthermore, the rotating means is so arranged that it operates just the same whether the tool is being fed vertically or horizontally, and at whatever angle the tool-holder is held.

My invention is illustrated in the accompanying drawing, in which,

Figure 1 is a vertical cross-section of the cross-rail and tool supports of a planer equipped with my invention; Fig. 2 is a plan view of the saddle and carriage; Fig. 3 is a plan-sectional view of Fig. 1, taken on two different planes; Fig. 4 is a side elevation of so much of a planer as is necessary to illustrate my improvements; Fig. 5 is a sectional detail of the friction feed mechanism; Fig. 6 is a partial front view of the tool-holder, and Fig. 7 is a front-view of Fig. 1 with the tool-holder removed.

In these views, 1 represents the cross-rail and 2 the saddle mounted thereon for horizontal movement, the screw by which said saddle is fed being represented at 3. Mounted in ways on said saddle for vertical movement is the carriage 4, said movement being imparted, either automatically or by hand, from the shaft 5, which is connected, in the usual way, by bevel gears with a vertical feed-screw 61, engaging a nut, not shown, on the carriage 4. A circular way 6 is-formed in the face of said carriage 4,`and in said Specification of Letters Patent.

way is mounted for circular adjustment a tool-holder 7, rotatably mounted within which is a sleeve 8, having a ring 9 secured to it below its bearing in the tool-holder and a bevel-gear 10 secured to it above said bearing. A tool-shank 11 is slidably mounted within the sleeve 8, being keyed thereto so as to rotate therewith and carrying the toolclapper-box 12 at its lower end. The shank `11 is vertically adjusted in the sleeve 8 by means of a screw 13, swiveled to said shank and engaging in a nut 14 held in the tool- `holder 7. The ring 9 has a lug 15 projecting from it, which comes alternately into contact with abutnients 16 and 17 formed on the .holder 7, as shown in Figs. 3 and 4.

Bevel-gear 10, on the sleeve 8, is in mesh with a bevel-gear 18, carried upon a journal 19 projecting from the tool-holder 7 concentrically with the axis around which said vtool-holder is angularly adjustable, said gear 1 8 having formed thereon a second set of teeth which mesh with those of another bevel-gear 20, which is splined to a vertical shaft 21, and carried in a bearing formed on the carriage 4. The shaft 21 is j ournaled in bearings on the saddle 2 and carries a spur-gear 22 on its end, which meshes with a similar gear 23 carried by a short shaft 24, likewise journaled in the saddle and carrying a bevel gear 25 on its other end. Two oppositely-facing bevel-gears 26, oneI of which is shown in Fig. 1, carried by a horiaontal shaft 28, are in mesh with gear 25,

which is thereby turned in one direction or,

the other according as to which of the gears 26 is clutched to shaft 28 by the clutchsleeve 29, which is slidably keyed to said shaft, and is moved by a fork 30, )rojecting from a bar 31, which is slidably mounted on the saddle 2 and can be clamped in adby a `bolt 32. The purpose of the two gears 26 and clutch is to enable the tool to be properly reversed at the beginninfr of the cutting stroke in either direction. haft 28 carries also a spur-gear 33, see Fig. 4, which meshes with a like gear 34 on a parallel shaft 35, on which is also a pinion 36, with which engages the vertically-guided rack 37. They lower end of this rack is connected by a link 38 with a crankpin 39 carried by a gear 40, which is in mesh with a gear 41, the pitch diameter of which is one-half that of the gear 40. The gear 41 is carried by one of the driving-shafts 44 of the pla-ner and is connected frictionally ica thereto by the 'strap 4Q, which surrounds a friction sheave 43 keyed to sladrshaftf The arrangement of these parts is shown in XFig.
